  Brier
     This word occurs frequently, and is the translation of several
     different terms. (1.) Micah 7:4, it denotes a species of thorn
     shrub used for hedges. In Prov. 15:19 the word is rendered
     "thorn" (Heb. _hedek_, "stinging"), supposed by some to be what
     is called the "apple of Sodom" (q.v.).
       (2.) Ezek. 28:24, _sallon'_, properly a "prickle," such as is
     found on the shoots of the palm tree.
       (3.) Isa. 55:13, probably simply a thorny bush. Some,
     following the Vulgate Version, regard it as the "nettle."
       (4.) Isa. 5:6; 7:23-25, etc., frequently used to denote thorny
     shrubs in general. In 10:17; 27:4, it means troublesome men.
       (5.) In Heb. 6:8 the Greek word (tribolos) so rendered means
     "three-pronged," and denotes the land caltrop, a low throny
     shrub resembling in its spikes the military "crow-foot." Comp.
     Matt. 7:16, "thistle."
